It sounds like in your situation there is some shadiness going on, so my comment isn't directed towards your situation. There seems to be a lack of proper coaching at your school.
I think every program and every coach should have the ability to choose their own team. I do and always have. I am the one that knows what I am looking for, I am the one that works with these kids 4 - 6 days a week for an entire year, no one is going to tell me who they think should be on my squads but me. Do I have favorites - yes, every coach does. My favorites are those that show up and do what they're supposed to do. Can it and does it change every day? Yes. Anyone can be a favorite. If I have issues with you all season long, you better bet it will effect your tryout. Can you imagine a football, baseball, basketball coach etc giving the power to choose their team over to someone they don't know? No. I feel for any school that is required to use outside judges, especially when at least 90% of those "outside judge tryouts" are rigged to the high heavens anyway! Save yourself the money, own your decisions, and do it yourself. Just my 2 cents.
